-in view context
select the box
"Hide the dependent if the dependency is not triggered "

then I just had to revert my conditions values to match the expected behaviour.
I didn't get it directly because I was looking for the opposite :
"Show the dependent only if the dependency is triggered "

I would like to reopen the discussion because the form state: unchanged
in edit context settings doesn't fully solve the issue.

The field stays visible but I can't modify its value when the form state is "unchanged"

I would like a setting for the "form state" in edit context that is "editable" whatever the condition...
Indeed, the objective of the condition in my case is only to control the view settings, not the edit settings
